RE: DMA on optical drive

I mentioned that no ATA is involved here. HA! (Shows how much I now about the hardware.) I thought that this 'ATA' was some new-fangled technology. Well, hdparm stated that these CD drives are atapi.

Mikkel:
Well, it depends on the drive. Not all optical drives support DMA,
but any fairly new drive should. You can use hdparm to see the
current settings, check what the drive supports, and to change the
current settings. Depending on your BIOS, it may also possible to
set DMA support for a specific drive. To get good performance from
your drive, you will want DMA turned on.

I checked the bios - only 'on' and 'off'. No way to select the unit.

hdparm states that these drives support sdma0-2 and mdma0-2, and that mdma2 is enabled.

I couldn't figure out which parameter to use to change the setting.

Here is what I'm working from:

Yes, I'm sure that my kernel wouldn't have this (old) problem. Btw - how do I check the kernel version?

This is exactly what I get!

ICIM - I have FC 6 and use gnome.
